Hi,

We attempted to initiate a TN3270 transaction in mainframe thru bridge link program, DFHL3270.

We are unable to initiate the user transaction via the bridge program, DFHL3270 though all the necessary setup activities are done. We are not able to identify the root cause of the issue which is failing with AEXZ abend in DFHL3270 called Assembler program.

Below are the steps we followed for DFHL3270 bridge setup:

1)Defined the SIT parameters as specified in the IBM manual as per the link below

http://publib.boulder.ibm.com/infocenter/cicsts/v3r1/index.jsp?topic=%2Fcom.ibm.cics.ts31.doc%2Fdfhtm%2Fdfhtm29.htm


2)Defined the bridge facility by allocating the DFHBRNSF file, CICSTS31.CICS.CICSM.DFHBRNSF as per the link below:

http://publib.boulder.ibm.com/infocenter/cicsts/v3r1/index.jsp?topic=%2Fcom.ibm.cics.ts31.doc%2Fdfhtm%2Fdfhtmgm.htm

Following IBM sample programs are available in our CICS region (CICSM)

DFH0CBRC ( COBOL sample business client ) ,DFH0CBRL( COBOL sample bridge client ) and BRCO ( Transaction to drive DFHC0BRC )

Before invoking the sample client program (transaction – BRCO), sample application (NACT transaction) has been setup by installing all the components as per the manual.

We are getting AEXZ abend in DFHL3270 called Assembler program.I have attached the dump analysis output for the AEXZ abend.Please help in giving your inputs for this resolution.

Thanks

Praveen Jaikumar

Please let me know on the same.

A similar question was posted one week ago. Do you either of you know one another? You're both located in Chennai. Suspicious.... icon_eek.gif

Have you done what the manual says yet?

Use the transaction dump to determine the cause of the failure. For further assistance, or if module DFHDUIO is not loaded and no transaction dump is available, contact your system programmer.
If you do not know how to analyze a transaction dump, contact your site support group. Or, you can pay a consultant to analyze the dump for you.

Hi Bill,

The earlier post on this CICS bridge was done by our application team support and they dont know much on the system side of CICS.

WE have taken the transaction dump for the AEXZ abend and the same was attached on the doc in my problem statement.

We are still finding a solution to analyze the dump as we are not sure how to analyze the dump and find the root cause.

What I wanted to know is from the CICS dump which i had given is there any problem reported ? Please let me know on the same,

thanks

Praveen

While debugging the AEXZ abend in the bridge link program, we ran the IBM utility (DFHDU630) to extract the CICS abend dump and found that the application is failing with KERNERROR during ALLOCATE_BRIDGE_FACILITY in the DFHBRNS utility. It’s also failing with KERNERROR in the DFHBRFR utility

On further analysis found that, this failure is happening in DFHBRNS module as per the below found from the IBM Trace Entries document.

Point ID Module Lvl Type Data
====== ====== === ==== ====
AP 4A61 DFHBRNS BR 1 EXIT 1 DRNS PARAMETER LIST
AP 4A01 DFHBRFR BR 1 Exit 1 BRFR parameter list


To our analysis we have got from the cics transaction dump, which i have attached in the document.

Not sure about a resolution of this error as per the dump.

regards

Praveen

FWIW, CICS Transaction Dump Utility DFHDU630 is for CICS/TS 2.3 (Version/Release 6.3). You need DFHDU640 for TS/3.1 (Version/Release 6.4).

To validate your code, try running the Load Module Scanner Utility DFHEISUP, using the IBM-supplied table DFHEIDBR.

You can find out more about LINK3270 Programming Considerations as well as other information in the CICS/TS 3.1 Operations and Utilities Guide (DFHA6B02) -

Thanks Bill for your post..

After checking the dump closely, we were again able to identify the root cause.When checked the file entry for DFHBRNSF was only having read access enabled. We didn’t give all access to this file entry when it was created.

We had enabled all the access which includes the update access to this file entry (CICSTS31.CICS.CICSM.DFHBRN ) and enabled the File entry in CICSM.

We had then submitted the BRCO transaction and we are not getting the AEXZ issue now as shown below and there is no ABEND..

Now the BRCO , IBM supplied transaction for the CICS Bridge 3270 works fine.


Thanks for everyone for their help !

regards

Praveen
